This invention relates to locks for car doors.

It is an object of the invention to provide a lock for car doors bywhichsaid doors may be forced into their fully closed position.

A further object is the provision of a lock for car doors, which willinsure maintenance of said doors in fully closed position.

Other objects of the invention will become apparent from the followingdescription thereof:

In the drawings forming a part of the specification, Y

Figure 1 is a fragmentary elevation of a car door lock embodying'thisinvention in its application to a double door construction, the lockbeing shown in operative position.

Figure 2 is a view similar to Figure 1, illustrating the lock ininoperative position.

Figure 3 is a view similar to Figure 1, showing the hasp of the lock inoperative position and the locking pin partly withdrawn to betterillustrate the relationship of th pin and the hasp.

Figure 4 is a sectional view taken on line 44 of Figure 1.

Figure 5 is a sectional view taken on line 5 5 of Figure 6.

Figure 6 is a sectional view taken on line 6`6 of Figure 4.

In the drawings the preferred embodiment of the invention is shown inits application to a double door construction. It is to be Vunderstood,however, that the lock is not limited in its application to such doubledoor .construction but is capable of utility as well with asingle doorconstruction. In the double door structure illustrated there is provideda main door 10 and an auxiliary door 11. The auxiliary door may besupplied with a jamb 12 movable therewith and in which a filler post ornailing stri-p 13 may be seated. Stiffeners 14 may be utilized in themain and auxiliary doors.

Applied to the auxiliary door 11 is a lock 1931. Serial No. 530,508.

plate 15 which may be secured thereto by means of a plurality of rivets16-16 extending through said lock plate, the door and a backing plate17. The lock plate is provided with a guideway 18 adapted to slidablyreceive a locking pin 19. The lock plate 15 is further provided with apair of vertically spaced ianges 20-21 extending forwardly thereof andconnected by means of a retaining wall 22 which lies in spaced relationto the lock plate.

Secured to the main door 10 by means of a plurality of rivets 23L is ahasp fastener 24. The rivets 23 extend through said fastener, the doorand the backing plate 25. Said fastener is preferably provided with aforwardly extending boss 26 upon which a hasp 27 is adapted to besupported. The hasp 27 is provided with an elongated slot 28 wherebysaid hasp vis adapted to have bot-h pivotal and sliding movementrelative to said boss. The hasp is retained in position upon the boss bymeans of a washer 29 retained in position by means of a rivet 30. On theface of the hasp presented toward the door a recessed portion 31 isprovided. By means of this recessed portion there is presented a pair ofspaced substantially vertical walls 32 and 33, respectively, the latterof said walls or abutments being positioned preferably adjacent the freeend of said hasp and being inclined.

The locking pin 19, as hereinbefore pointed out, is slidably retained inthe guideway 18 provided in the lock plate 15. The pin 19 isadditionally retained against removal from the guideway 18 by means of aboss 34 extending from said lock plate and through an elongated slot '35formed adjacent the lower portion of said pin. A washer 36, larger indiameter than the width of the slot formed in the pin 19, is retainedagainst the boss by means of one of the rivets 16, thereby preventingwithdrawal of the pin from the guideway formed in the lock plate.Intermediate the ends of the pin a projection 37 is formed, thisprojection having spaced walls 38 and 39, the latter being inclined tothe vertical in conformity with the inclined wall 33 provided on thehasp. The upper end of the pin is formed with a flange portion 40 and adoor.

In order to close a door opening provided in a house car by means of thedoors n and 11 the auxiliary door 11 will first be moved to closedposition. The 1main d oor will then be moved toward closed position.Assuming,

however, that the main door cannot be moved to its fnlly closed positionthe lock construction above described may'be'utilized Afor this purposewithin the limits of thelo'ck To accomplishithisi'resultthe hasp'may bemoved to' t e position shown in'dot and dash lines in Figure 2 of .thedrawings and then moved substantially horizontally until it ispositioned in supporting relationship'upon the flange 21 and'bet'wieenthe retaining wall 22 andthe lock plate.v Prior to this placement pf`the hasp the pin 19 will have been elevated to the position shown inFigure 2 `of the drawings, the pin yin thisv movement lpassing through arecess Il., -,clearly shown in Figure 6 of the dra-wingsv andl formed intlieu'pper flange 2O iof the lock plate. The pin will then be lowereduntil the projection 37 provided thereon .enters the recessed portion 31formed in the hasp.y The ,pin may ythen be driven downwardly duringwhich 'movement the hasp and, consequently, the ldoor to which it issecured will be forced to fully closed position. This is effected by nieans of .the engagement between the inclined vWall l39 formed yon theprojection 37 and the inclined ,wall a3 3 provided yby the recessedportion 31 on the h asp. For the purpose of driving said pinto homeposition the fia-nge 40 is fplvidd at the Yupper end thereof. It isapparent that when said door has once been drawn to its fully closedposition it will be rigidly retained in such position againstback-andforth movement when the l'car is .inv transit. It is manifestfroml Figure 4 of the drawings that because of the engagement betweenthe right hand Aend of the lhasp andV the boss ,formed Ion the haspfastener nomovenient of the door toward the right can result.YFuitlierinore, inasn'iuohas the twoV d oors as shown in this figure areno w in engagement the door 10 cannot move toward' the left; y i

llVhilea preferred embodiment vof this inf vention has been set forth itis to be understood that the invention is not to limited to the detailsof construction shown. It is intended that all changes and modificationsfalling within the spirit of the invention are covered herein and thatno limitations other than those included in the claims appended heretoare to be imparted to this invention.
